Water Leaking, help.

Hello to all the members of cafelat robot. I would like you to enlighten me on something that concerns me and is starting to tire me regarding the cafelat robot. I bought the cafelat recently and sometimes I have water leaking, it's very annoying to have prepared the coffee and in the end you can't make coffee because of the above problem. The seal has been installed correctly from the factory, I have no issues with the portafilter. What could be the cause? Is there a case where a screw needs tightening? Is there some technique with the handles? Am I pressing wrong? I am also uploading some photos with the screws and the seal. Thanks in advance. I am waiting for your answers.
